SPECIFICATION formngvpart Of Letters Patent NO. 708,022, dated September2, 1902.

Application tiled August 3, 1901. Serial No. 70,710. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, FRANK CARTLIDGE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Lubricators, of whichthe following is a specification.

This invention relates to lubricators or oilers for lubricating machinesof various kinds and is especially designed to furnish means whereby oneor more bearings or devices may be supplied with oil fromacommon sourceof supply and means whereby the oil will be allowed to iiow when themachine is started and stopped as the machine is stopped or a determinedamount of oil brought into position to be presented to one or morebearings.

It consists inl the novel combinations and such operative mechanism aswill be more speciically described and claimed hereinafter.

In the drawings, Figure lis a sectional view of a lubricator embodying aportion of this invention. Fig. 2 is a plan viewof the same. Fig. 3 is asectional view on the line 3 3 of Fig. l. Fig. 4 shows a modified formof construction. y Y

A represents an oil-receptacle adapted to contain a supply sufficient torun the machinel anydesired length of time. It is provided with lugs a afor attaching to a convenient support. A vertical valve-stem b, runningthrough the receptacle, is secured to a valve B, provided with one ormore chambers b' and a depending tubular extension h2 of smallerdiameter. The valve B and' its extension b2 it in a casing o. at thebottom of the receptacle A. A by-pass a2 in the casing leads from thereceptacle to a point below the valve and is adapted to furnishcommunication at times through an opening b3 in the tube h2 and fromthence th rough a pipe C to the bearing to be oiled. Ports a3 in thecasing register at times with the chambers b and furnish means forilling said chambers. As the valve is oscillated said chambers arebrought to register with openings to outlet-pipes D D', which run tobearings to be supplied with a determined amount of oil. The upper endof the stem h passes out through a bearing in 5o the top of thereceptacle A and has an armature E secured thereto. Electromagnets F F"are mounted on brackets f f on the receptacle A in such position as toattract the ends of the armature E and oscillate the stem b. AspringGholds the armature normally7 away from the magnets, and in this positionthe opening b3 is out of register with the by-pass and the chambers b'are in register with the ports 0.3, allowing the chambers to be filled;Whenv a current is sent through the coils of the electromagnets, the

armature is attracted, thc stem h is turned,

Aand the opening b3 brought to register with the by-pass, allowing theoil to iiow out through the tube C to the bearing. At the same time thechambers b' are brought to register with the openings to the pipes D Dand their contents allowed to discharge. A set-screw e in the armature Eis used to adjust the amount ofmovement of the stem, and consequentlythe iiow of oil.

In the moditied form of construction shown in Fig. 4 the lower end ofthe stem b is bored to form an outlet to the pipe C, and the oil isadmitted through a lateral opening b3, which registers with an openinga4 in a seat (1,5, pro-V vided at the bottom of the receptacle for thestem b. Normally the passage is closed; but

when the stem is turned and the openings within the scope of thisinvention, which I do not limit to the exact construction shown; but

What Iclaim is- 1. vIn a lubricating device, the combination of areceptacle, a casing at the bottom of said receptacle, inlet and outletports in said cas-l ing, a valve in said casing with chamberscommunicating alternately with said inlet and outlet ports, a tubularextension on said ing, a valve in said casing with chamberscommunicating alternately with said inlet and outlet ports, a tubularextension on said valve, a by-pass leading from the receptacle to saidextension, a lateral orifice in said extension adapted to register withsaid by-pass, a stem for said piston and means for turning said stem.
